Went for a ride car worked fine. Turned car off and did some erands came back started and car just kept dying. When it would run it ran very ruff and had to keep my foot on the gas. Thought we had ice in the lines so add gas-line anti-freeze. Still wouldn't start decent. Eventually got it started and it seemed to be running fine. When to the next stop, left the car ideling and it stalled. Had to tow it home. After letting it sit for 2 hours it started no problem. Went for a ride late the evening, no problems. Took it to church the next day, no problem. After the service tried to start it and it kept dying. Finally got it to run, it was pretty ruff, had to drive with both feet. (This is an automatic.) Got on the highway and it started to hesitate, put it to the floor and managed to keep it running. Tried to start it the next day, it will start but not stay running. You can hear the fuel pump making noise, so the pump is not completely dead.
Any ideas?
You could also check the fuel injector wires,sometimes they come loose if the clip broke somehow

I am having the exact same problem. My accelerator keeps acting like it is loosing power. I've tried pushing it down to the floor and it doesn't even make it budge. It also jerks really bad before it dies, which is scary makes me think something is really wrong with my transmission. I've left my car with two different mechanics for days. One mechanic kept telling me that there was just dirt on the sensors. The other mechanic told me it was my battery and put a new one in. Of course I'm still stuck in the same situation but one of my friends said to have the mechanic check into the accelerator sensor. I even asked my mechanic to and he didn't because he thinks it's the battery. Now I'm looking for a mechanic that will check the sensor for me.
I have the exact same problem with a 2001 pontiac grand prix GT 3.8 one of many problems put it on diagnostics and it says cracked or loose vaccum hose, defective mass air flow sensor or map sensor taking it to the shop tomorrow to find out which one it is LOve the car looks great and drives good when its running right but it has been an overall HORRIBLE!!!!! car
Had my 1998 Grand Prix fixed it was the mass air flow sensor. Tinny little box with a rather large price tag. Works great now.
I have a 1990 grand prix turbo, is will start but won't stay running longer than 30 seconds. Any Help
